Buoyancy Compensator Bladder With Underarm Low-Pressure Inflator Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing buoyancy compensator bladders are designed exclusively for either back mount or side mount diving, lacking a low-pressure inflator (LPI) positioned to run under the diver's armpit, which restricts versatility and requires reconfiguration when switching between diving modes.
Innovation Solution
A buoyancy compensator bladder design with the LPI positioned along the middle surface of the air cell, allowing it to run under the diver's armpit, enabling seamless transition between back mount and side mount diving configurations without repositioning or reconfiguration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the LPI is positioned on the outer surface of the air cell for back mount diving, then the inflator head is disposed on the front of the diver's chest, but the bladder cannot be used for side mount diving
Solution Approach 1:
The buoyancy compensator bladder is designed with a universal LPI positioning system that can accommodate both back mount and side mount diving configurations. The LPI is positioned on the outer surface of the air cell in a location that allows it to function effectively regardless of the diver's mounting orientation, eliminating the need for separate bladders for different diving styles.
Solution Approach 2:
The LPI is designed with flexible positioning capabilities that allow it to adapt to different diving configurations. The inflator can be positioned dynamically on the outer surface of the air cell in a way that maintains effectiveness whether the diver is in back mount or side mount position, providing operational flexibility.
2Adaptability or versatility
If the LPI is positioned on the outer surface of the air cell, then the structure allows easy use for back mount or side mount diving, but the bladder must be repositioned or reconfigured when switching between diving modes
Solution Approach 1:
The buoyancy compensator bladder incorporates a universal LPI design that eliminates the need for reconfiguration. The LPI is positioned on the outer surface of the air cell in a location that works for both back mount and side mount diving, so no repositioning or reconfiguration is required when switching between diving modes.
3Adaptability or versatility
If existing buoyancy compensator bladders are designed exclusively for back mount or side mount diving, then the design is simple and cost-effective, but the versatility is limited and requires equipment changes when switching modes
Solution Approach 1:
The buoyancy compensator bladder uses a simple yet effective universal design for the LPI positioning. By placing the LPI on the outer surface of the air cell in a specific location, the design maintains manufacturing simplicity while achieving versatility that supports both back mount and side mount diving without requiring complex reconfiguration mechanisms.

AI summary
A buoyancy compensator bladder includes an air cell, a connector, a low-pressure inflator (LPI), and at least one over pressure valve. The LPI which inflates and deflates the air cell is positioned on an outer surface of the air cell. As a result, when the fully assembled buoyancy compensator is equipped by a diver, the LPI runs from behind the diver's torso and under their armpit. This results in the inflator head which is part of the LPI to be disposed on the front of the diver's chest during back mount or side mount diving. This structure allows the bladder to be easily used for either back mount or side mount diving. The bladder may further be equipped with auxiliary/non-essential devices such as wight pockets/pouches.
